Error when using instantiated mxml component in popupmanager

Question

Hi,
Im getting the following error when trying to create a popup:
Error #1007: Instantiation attempted on a non-constructor
The code looks as follows
var browserPop:CustomBrowser = new CustomBrowser();
browserPop.targetType = "file";
browserPop.fileType = "jpg";
var pop:TitleWindow =
PopUpManager.createPopUp(this,browserPop as Class, true) as
TitleWindow;
Where CustomBrowser is an MXML component extending
TitleWindow.
If i use:
var pop:TitleWindow =
PopUpManager.createPopUp(this,CustomBrowser, true) as TitleWindow;
it works fine but i need to be able to set some public
properties and therefore instantiate it first. Any help would be
appreaciated.
Thanks in advance
Eric

Create you component using the popupmanager, then cast it to
the
specific type to access it's public methods and/or variables.
Like so for mxml component ExceptionPopup:
var popup:IFlexDisplayObject;
popup =
PopUpManager.createPopUp(_parentPanel,ExceptionPopUp,true,null);
(popup as ExceptionPopUp).addRecords(ev.errorMessage);
(popup as ExceptionPopUp).title = "title";
(popup as ExceptionPopUp).userText.text = "some user text"
PopUpManager.centerPopUp(popup);
